4 02XX: A new genus and species of armored scale insect (Hemiptera: Diaspididae) from Australia found in the historic Koebele Collection of the California Academy of Sciences John W. Dooley III United States Department of Agriculture Animal and Plant Health Inspection Service Plant Protection and Quarantine 389 Oyster Point Blvd, Suite 2A South San Francisco, CA john.w.dooley@aphis.usda.gov Gregory A. Evans USDA/ APHIS/ PPQ c/o Systematic Entomology Laboratory Bldg 005, Room 137, BARC-WEST Baltimore Ave. Beltsville, MD Abstract. A new genus and species of armored scale insect (Hemiptera: Diaspididae), Protomorgania koebelei Dooley and Evans, is described and illustrated from specimens collected by Albert Koebele on Pittosporum sp. (Pittosporaceae) in Australia around the year A key to the genera of armored scale insects similar to Protomorgania and known to occur in Australia is provided. Key words. Aspidiotinae, Coccoidea, taxonomy Introduction Albert Koebele was sent by the U.S. Department of Agriculture (USDA) to Australia around the year 1900 to search for natural enemies of various species of exotic scale insects (Hemiptera: Coccoidea) that had become pests in California (Boardman 1977). In the process of collecting natural enemies, he also collected many specimens of scale insects (Weathers and Lawton 1982). The senior author examined Koebele s collection of armored scales at the California Academy of Sciences Collection in San Francisco, California (CASC). Upon examination of specimens processed and slide mounted from the dried specimens in the collection, a new genus and species of armored scale insects was discovered and is here described. Material and Methods The method used for preparation of slide mounted specimens follows that used by Gill (1997), Miller and Davidson (2005), and the Systematic Entomology Laboratory (SEL), USDA (Anonymous 2006). Specimens of adult female armored scales were placed into test tubes containing 5% KOH and heated in a bubbling hot water bath for 15 minutes. They were then washed in water to remove potassium hydroxide and soaked in Essig s aphid fluid with the addition of two drops of double stain for minutes. The stained specimens were placed in 70% ethanol for 15 minutes and then transferred into 90% ethanol for 10 minutes. Specimens were transferred to clove oil for 15 minutes prior to slide mounting in Canada balsam. Images and measurements were taken with a SMZ 1500 wide field and a Nikon Eclipse 80i compound microscope using a Nikon DS-Fi1 Digital Image camera. Measurements were taken from 4 specimens and given in micrometers (μm). Specimen Depositories.

Morphology and Terminology. A glossary for the morphological terms used to describe armored scales can be found in Miller and Davidson (2005). The following abbreviations are used: abdominal segments 1 through 8 (A 1 -A 8 ); cephalon (C 1 ); pygidial lobes median or first lobe (L 1 ), second lobe (L 2 ), third lobe (L 3, ) and fourth lobe (L 4 ); perispiracular pores (pps); perivulvar pores (pvp); and thoracic segments prothorax (T 1 ), mesothorax (T 2 ) and metathorax (T 3 ). Key and illustrations A key to the genera of armored scales known to occur in Australia that are similar to Protomorgania n. gen. is provided. The genera in this group belong to the subfamily Aspidiotinae and are characterized by having a broad body with a constriction or incision between the prothorax and mesothorax. The metathorax and abdomen are usually broader than the region from the anterior margin of the body to the mesothorax. In addition, most of the species in this group lack perivulvar pores and unlike most of the species in other aspidiotine genera which lack perispiracular pores, many of the species in this group have perispiracular pores present at least above the anterior spiracle and sometimes above the posterior spiracle. Illustrations of the type species of the genera similar to Protomorgania are provided to assist the readers with the key. All of the illustrated species are known to occur in Australia (Brimblecombe 1954, 1956, 1957, 1959, Ferris 1937 and MacGillvray 1921) with the exception of Pseudaonidia duplex (Cockerell) (Cockerell 1897 and Ferris 1937) and Duplaspidiotus claviger (Cockerell). Each of the plates of the various genera includes the habitus of the adult female, a detail of the pygidium and a detail of the left side of the pygidial lobes and paraphyses.

A) habitus; B) tubercle; C) anterior spiracle; D) posterior spiracle; E) pygidial lobes; F) slide mounted female habitus; G) habitus on host; H) close-up of habitus on host Protomorgania Dooley and Evans, gen. nov. Type species. Protomorgania koebelei Dooley and Evans, sp. nov. Diagnosis. Protomorgania Dooley and Evans is a monotypic genus that belongs to the subfamily Aspidiotinae based on presence of macroducts of the 1-barred type. Unlike many of the aspidiotine genera, it has perispiracular pores associated with the spiracles. It is similar to several of the genera treated herein in that they have a relatively broad body with a constriction or incision between the prothorax and mesothorax with most of the species in this group lack perivulvar pores. It can be distinguished from these genera by the following combination of characters: anterior and posterior spiracles with associated perispiracular pores; dorsum of the pygidium not reticulated; L1 lobes fused ventrally, appressed dorsally. It is most similar to Neomorgania (MacGillvray, 1921) but can be distinguished from that genus by having: the anterior and posterior spiracles with associated pores; L1 lobes fused ventrally, appressed dorsally; and a tubercle present on lateral margin of the cephalon; in Neomorgonia, only the anterior spiracles have associated pores; the L1 lobes are appressed ventrally and dorsally; and it lacks the tubercle on lateral margin of the cephalon. Adult female Description. Habitus in nature. Individuals abundant, found on bark and somewhat cryptic in appearance being similar to the color and texture of the bark. Exuviae brown, oval and subcentral.

A) anterior perispiracular pores; B) dorsal microducts; C) dorsal microducts, magnified; D) roughened cuticle. Slide mounted adult female. Specimens with a deep prothoracic-mesothoracic constriction with the anterior margin uniformly dome-shaped. Abdomen broadly rounded with the pygidium slightly more sclerotized and cuticle stippled. Clusters of disc pores associated with the anterior and posterior spiracles. Pygidium with only median lobes that are broad, short and appressed; L2 and L3 absent. 1-barred dorsal macroducts present. Perivulvar pores absent with the pygidium marked by dorsal sclerotized arch anterior to the vulva extending laterally on each side of and beyond the vulva. Etymology. Genus name from the Latin word proto meaning first, which refers to the species being collected by Koebele before the discovery of the genus Neomorgania.

Protomorgania koebelei Dooley and Evans sp. nov. (Fig. 1, 2, 3) Diagnosis. Protomorgania koebelei is currently the only species described within the genus. It is described with the following combination of morphological characters: perispiracular pore clusters associated with both the anterior and posterior pair of spiracles; dorsum of pygidium finely stippled, not reticulate; only one pair of pygidial lobes (L 1 ) present, which are appressed, contiguous and joined basally; a single simple plate present on pygidium between L 1 and the position of the L 2 seta. Adult female Description. Habitus in nature. Armored scales abundant on the bark with female exuvia oval and brown in color with shed skins subcentral (Fig. 1). Slide mounted adult female (Fig. 1, 2, 3). Specimens range from μm in length and from μm in width. Cuticle ornately and finely stippled. Cephalothorax with deep mesothoracicmetathoracic constriction; area above constriction broadly rounded and dome-shaped. Antenna with one seta; minute tubercle present (absent in some specimens) on lateral margin and anterior to mouthparts and anterior spiracle. Each anterior spiracle associated with a cluster of perispiracular pores; each posterior spiracle associated with cluster of 8 12 perispiracular pores and cluster of microducts situated from below and adjacent to spiracle, extending into the submedian area between posterior spiracle and margin. Pygidium chitinized and finely stippled around vulva, broadly rounded from metathorax to pygidial apex. Single pair of appressed broad, short median lobes (L 1 ) present. Apex with single glandular plate located between L 1 and position of seta occupying L 2 position, does not extend beyond apex of L 1. Two small clusters of microducts extend along submedian region to submargin of A 1 segment and continue as a band of submarginal microducts extending from A 2 to almost beyond A 7. Perivulvar pores absent. A sclerotized arch that consists of 5 6 sclerotized striae present above and extending around vulva, terminating between vulva and posterior apex of body. Vulva area finely stippled. Anal pore located directly anterior to, and almost touching, basal area of median lobe, and bounded by an inverted v-shaped structure. Distribution. Australia (Victoria). Host. Pittosporaceae: Pittosporum sp.

Melbourne, Australia on Pittosporum sp. 18- xii-1890 (Koebele collection # F1972) deposited at the CASC. Paratypes (24 adult females), Melbourne, Australia on Pittosporum sp., 18-xii-1900 (Koebele collection # F1972). Two adult females (two slides) deposited at ASCU, five adult females (one slide) deposited at CASC, five adult females (one slide) deposited at USNM, six adult females (2 slides) deposited at PPQC, 3 adult females (one slide) deposited at FSCA, and three adult females (two slides) deposited at CDFA. Etymology. This species is named in honor of Albert Koebele. Discussion. The finding of Protomorgania koebelei is especially important because it shows that the study of specimens that have been stored away in collections for over a hundred years may result in the discovery of new taxa. Protomorgania koebelei appears to have several taxonomic traits, such as the constricted thorax, that are common to other endemic Australian genera. Brimblecombe described many of the genera and species treated herein; however, no comprehensive keys to the genera or species of armored scales of Australia have been published. It is possible that once other species are discovered and the morphological and molecular characteristics of the species are better understood, that some of these genera may prove to be synonymous. We have not attempted to make such decisions based on the small number of species known in most of these genera and the lack of detailed morphological and molecular studies.
